And with the stones he built an altar in the same of the
Lord,
&c.] Whom the twelve tribes had formerly worshipped; and
though now divided in their civil state, yet ought to be united
in the worship of God:
and he made a trench about the altar, as great as would
contain two
measures of seed;
or two seahs, one of which was the third part of an ephah, and
two of them were more than half a bushel; and this trench or
ditch round the altar was as broad as such a measure of seed
would sow.
